拿 4G 网络连接我的 VPS，ssh 一连接就掉。咨询了下 Vultr 的客服。回复如下: We have received reports of similar behavior/performance from your specific geographical region. Our testing to date indicates this is an issue at the regional ISP level, which is 100% outside of our control. All Vultr infrastructure is performing optimally. You can try logging in and using the web console.
You can also snapshot your instance and redeploy it if you wish to obtain a new IPv4 address, because we cannot manually assign IPv4 addresses. Make sure that you set your instance's network adapter to DHCP mode before taking the snapshot, as static IP assignments will need to be corrected otherwise. We appreciate your understanding regarding this matter.
